加载GridPanel根据特定的值将复选框选中

代码如下

    var gridArray = new Ext.grid.GridPanel({
        title: '选择单据',
        cm: col,
        sm: sm,
        store: store,
        autoScroll: true,
        viewConfig: {
            forceFit: true,
            columnsText: '显示的列',
            scrollOffset: 20,
            sortAscText: '升序',
            sortDescText: '降序'
        }
    });
    gridArray.store.on("load", function() {

        var p = store.getRange();
        for (var s = 0; s < p.length; s++) {
            if (p[s].get("CHECKFLAG") == "Y") {
                gridArray.getSelectionModel().selectRow(s, true);
            }
        }
    });
